mellanox network cable MCA4J80-N005 AOC Cable IB Twin Port NDR up to 800Gb/s 5m cables for mellanox network MCA4J80-N005

mellanox network cable MCA4J80-N005 AOC Cable IB Twin Port NDR up to 800Gb/s 5m

MCA4J80-N005 is a 800Gb/s twin-port OSFP (Octal Small Formfactor Pluggable)-to-2x400Gb/s twin-port OSFP Active Copper Cable (ACC) for InfiniBand NDR networking.

MCA4J80-N005 ACC cables are the second lowest-cost, lowest-latency, very low power consuming, high-speed links available due to their simplicity ofdesign and minimal components. The “active” term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 3, 4, and 5 meters while maintaining very low-latency and very low-power at 1.5 Watts per end. Thin 30AWG is used for 4m lengths and thicker 26AWG for 5m. Each end includes an EEPROM which provides product identification and characteristics to the hostsystem. For lengths less than 3 meters, use passive DAC cables.

An ACC is a passive DAC with a pre-emphasis equalizer IC included in each end, enabling cable lengths of up to 5 meters while maintaining very low-latency and very low-power at 1.5 Watts a per end. Every cable length is tuned to reduce signal noise and back reflections. The ACC firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to.

MCA4J80-N005 cable solutions provide power-efficient connectivity enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers. Rigorous cable production testing ensures best out-of-the-box installation experience, performance, and durability.

MCA4J80-N005  Applications

2x400Gb/s

Quantum-2

InfiniBand or

Spectrum-4 Ethernet

switch-to-switch and

switch-to-DGX-H100

The main use case for the MCA4J80 is to link two 800Gb/s Quantum-2 switches to each other (up to 5-meters). The 3-meter, flat and finned-top cable is for linking Quantum-2 switches to DGX-H100 Cedar systems.FCC Class A NoticeThis equipment has been tested and found to comply with the limits for a Class A digital device,pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protectionagainst harmful interference when the equipment is operated in a commercial environment.

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used inaccordance with the instruction manual, may cause harmful interference to radio communications.Operation of this equipment in a residential area is likely to cause harmful interference in whichcase the user will be required to correct the interference at his own expense.Handling Precautions and Electrostatic Discharge (ESD)The cable is compatible with ESD levels in typical data center operating environments and certifiedin accordance with the standards listed in the Regulatory Compliance Section.

The product isshipped with protective caps on its connectors to protect it until the time of installation. In normalhandling and operation of high-speed cables and optical transceivers, ESD is of concern duringinsertion into the QSFP cage of the server/switch. Hence, standard ESD handling precautions mustbe observed. These include use of grounded wrist/shoe straps and ESD floor wherever a cable/transceiver is extracted/inserted. Electrostatic discharges to the exterior of the host equipmentchassis after installation are subject to system level ESD requirements.Cable Management GuidelinesIt is important to follow the instructions and information detailed NVIDIA Cable ManagementGuidelines and FAQ Application Note to insure proper and optimal installation of this cable and avoidphysical damage.
